A rock and roll sleazefest isn't for everyone, though. Grady Champion's less aggressive, less offensive blues might be an easier choice. He's back in town after a tour supporting his latest Shanachie release Payin' for My Sins, giving an all-too-infrequent local performance at the relatively new Rhythm Room Café (239 Sunny Isles Blvd.) on Saturday (nights up there have been too quiet for too long). The show starts at 10:00 p.m. Admission is free. Call 305-919-8080.
